Swelling Earth population? Desire to relocate to a distant solar system? No problem, just get your star ship ready, as scientists say they have found a new exoplanet that may have the right conditions to support life. The new planet called HD 40307g is part of a six-planet system.

akA new spin on 3D printing technology could have spacecraft building themselves by taking materials from space junk or asteroids. The "SpiderFab" project has received $100,000 from NASA's innovative Advanced Concepts program to determine the feasibility of such a self-construction design. With some planning and more funding they hope to launch a 3D-printing test mission within several years.

Eight years in planning and eight months in travel, NASA's Mars Science Laboratory landed safely on Mars, resulting in cheers from the NASA team and showing once again the true grit of American ingenuity and determination. The landing happened around 1:32 a.m. EDT. The Curiosity rover later sent the first images from the Gale Crater after landing.
